How do I display a tree of things in Bash?

Question

How do I make a tree of all things with bash? What is the command?

All things? It can be really hard. `tree` can be used for file system and `pstree` for processes. Possibly there are other `*tree` tools. Google can be invaluable here. — przemoc, Mar 15 '10 at 00:24

tree /

or

find /

Update: @OP, since you have so much trouble with it, how about this alternative. On ubuntu 9.10, you should have bash 4.0 ? so try this

#!/bin/bash
shopt -s globstar
for rdir in /*/
do
    for file in $rdir/**
    do
      echo "$file"
    done
done

If tree isn't installed on your Ubuntu machine use: `sudo aptitude install tree` – Ben S Mar 15 '10 at 00:23
the same...0 packages installed :S – pedro Mar 15 '10 at 00:26
findutils is a dependency of libc6, which many, many core packages (including apt!) depend on. And Ben gave correct instructions for installing `tree`. So I'm not sure what's going on. – Matthew Flaschen Mar 15 '10 at 00:39

The tree package (http://packages.ubuntu.com/karmic/tree) is part of the universe packages, which might not be enabled. I would ask this question on the Ubuntu forums as it's not strictly programming related and they would likely already have resources to point you towards to help you out. – Ben S Mar 15 '10 at 00:43

you should probably alias this :)

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/ /' -e 's/-/|/'

(Warning: huge output)

$ find . -print | sed -e 's;/*/;|;g;s;|; |;g'

Add alias to ~/.bash_profile

alias tree="find . -print | sed -e 's;/*/;|;g;s;|; |;g'"

tree -R /

On a related note, to stop the command, press CTRL+C

Like I commented to ghostdog74's answer, install it with this command: `sudo aptitude install tree` – Ben S Mar 15 '10 at 00:26
i already try to install...after i write tree and says is not installed – pedro Mar 15 '10 at 00:29
@pedro You need to `hash -r` or open a different terminal in order to refresh which executables are on the path. – Jack G Aug 05 '20 at 23:09

Assuming you want to find something from tree, do

    tree / > tree.txt

Then Ctrl + F it.
